to be honest, i don't wear red lips very often; mainly because i found it very difficult to find the perfect red, just like the young lady in the blog you posted.
like her, i have green veins and warm skin. but instead of looking for orange-reds, i go for bronze reds with brown undertones. actually, my ideal shades do seem to be brown-undertones across the board; even my pinks are brown and yellow like Viva Glam 5 and Hug Me. (almost every lipstick i own comes from MAC - quel surprise! non?)
other than Ruby Darling, my next red is Fresh Moroccan. they are both frost finishes and Fresh Moroccan is lighter and more red while Ruby Darling has more of the bronze to it!
